Application January 2, 1946, Serial No. 638,616

This invention relates to means for supporting package holders on a suitable carriage mounted on trackways on the side of a twisting frame, spinning frame, and the like, there being provision for two upper package holders and two lower package holders, the upper preferably being filled with complete packages of yarn ready to be installed in the machine while the lower are provided for receiving the empty bobbins,.spools, and the like in a dofling and donning operation.

' It is an object of this invention to provide suitable trackways on the side of a twisting frame, a spinning frame, and the like and having a wheeled carriage mounted thereon for travel along the trackways, said carriage having means for supporting two pairs of package holders, one pair usually being occupied by filled packages ready to be installed in the machine while the other pair of package holders is adapted to receive the exhausted packages or spools which are removed from the machine in a domng and donning operation. l

It is another object of this invention to provide in a twisting frame, spinning frame, and the like a wheeled carriage mounted on one side of the frame and movable along the entire length of the frame and having means for detachably supporting package holders for placing filled packages into the machine and for receiving empty bobbins, spools, and the :like which have been processed in the machine.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when takenin connection with the accompanying drawings, in which:

Figure 1 is a front elevation of a portion of a twister frame showing the trackway and the car-' .riage applied thereto;

Figure 2 is an end elevation of the machine and the carriage and spool carriers showing portions thereof broken away;

Figure 3 is a vertical sectional view taken along the line 3-6 in Figure 1 on an enlarged scale;

Figure 4 is a vertical sectional view on an enlarged scale and taken along the line 6-6 in Fig-' ure 1;

' Figure 5 is a vertical sectional view taken on an enlarged scale along the line 5-5 in Figure 1;

Figure 6 is a plan view of one end of one of the package carriers.

Referring more specifically to the drawings, the numeral I 0 indicates one of the upright frame members of a twisting frame, spinning frame, and the like, which has a plurality of spindles i'fl thereon, onto which packages of yarn 52 are placed for processing; many of the conventional features of the machine are omitted as they are not pertinent to this invention. The spindles H are driven in a conventional manner by a belt M. These packages of yarn it are usually wound on spools l3; and when one of the spools becomes empty it is necessary to remove the empty spool and place thereon a filled bobbinor spool it having yarn l2 thereon. This heretofore has been accomplished by rolling a truck down the aisle having two compartments, one for the re-' ception of the empty bobbins and the other for carrying new, filled packages to be placed on the spindles after the empty package has been removed. This is a laborious operation because of the stooping over and handling of these packages and, furthermore, it takes up a lot of room in the aisle, sometimes damaging the equipment'by rolling the truck into the mechanism of the twister and spinning frame. I

I have endeavored to overcome this dimculty by amxing a plurality of brackets it onto the machine and amxing an angle iron It on these brackets to.form an upper trackway. There is also secured to the framework of the machine another angle iron ii to serve as a lower-trackway. lhese trackways extend from one end of the machine to the other, and on these trackways, I mount a suitable carriage mechanism.

This carriage mechanism comprises a rectangular frame comprising angle uprights 36 and it having a horizontal strap iron 22 and bottom 23 and intermediate horizontal angle 28. All

of these pieces 2% to 2d are welded together to 32 and comes down and forms a covering for the make a unitary frame.

An intermediate horizontal strap 26 is also secured to the upright angles 26 and ti. Upright angles 26' and it have welded thereto suitable plates at at each upper corner thereof, to which is welded as well as being welded to strap iron 22, an inverted U-shaped member 32 having a a pin (-33 penetrating both legs thereof and on which is rotatably mounted a grooved wheelie which rides on the upright angle of upper angle trackway 86.

The intermediate angle Ed has a U-shapedpiece, of sheet metal indicated at 36 suitably secured thereto. as by welding or soldering, the U- shaped member 36 extending downwardly in the form of sheet metal cover 31. Also, a sheet metal cover 38 covers the inverted U-shaped member front side of the main frame of the carriage and extends downwardly and has a curved portion 39' which fits over the 'U-shaped portion, 36 of sheet 3 metal me lnber 81, all of these being suitably secured to the frame by riveting, soldering, and the like. The lower angle member 21 of the carriage has suitably secured thereto as by welding a U-shaped member 42 which is covered by lower curved portion of sheet metal member 31. This U-shaped member 42 has a suitable pin 43 therein on which is rotatably mounted a wheel 44, there being identical structures at each of the lower corners of the frame and like reference characters will apply.

The lower curved over portion of sheet metal member 31 is indicated at 31c and covers a U- shaped portion 40 fitting over the U-shaped portion 42. The wheel 44 is adapted to press by gravity against the upright portion of angle l4 which acts as a trackway for the lower wheels 44.

The upper portion of the carriage has secured on the outer surface of the sheet metal member 38 by means of suitable bolts or rivets penetrating the bar 22, a plurality of hooks 50, and the lower portion of the sheet metal member has secured thereto a plurality of hooks H which are riveted through or bolted through the sheet metal member 31 and secured to the strap member 26. Used in connection with this traveling framework, I provide a plurality of package carrler's indicated at 60. These carriers comprise a plurality of bars 6! with a cross bar 62 and end frames 63 and 64 and side bars 65 and 66 and corner braces 68. The bars 8| have a plurality of pins 61 uprising therefrom onto which the empty bobbins It or filled bobbins with packages of yarn l2 thereon are placed. The end frames 62 and 65 project upwardly a greater distance than the height of the bobbins and have handle portions on their upper ends adapted to be engaged by the two hands of an operator for lifting the same and placing them on the hooks i and for removing the same therefrom.

It is to be noted that the lower portion of the upper carrier rests on the projecting portion 38a; whereas, the lower portion of the lower carrier rests on the projecting portion 31a. This causes the packages or bobbins to be held on the pins 61 by gravity and prevents their jarring off and falling onto the floor.

Method of operation In operation, a carrier is filled with packages of yarn and placed on the upper hooks 50, and an empty carrier is placed on the lower hooks Si, usually this board is big enough to accommodate two filled carriers on the upper half of the traveling carriage and two empty carriers "on the lower half thereof. The carriage is then rolled along the length of the spinning frame .by moving it a short distance at a time, and the empty bobbins are removed from the spindles and placed in the lower carriers, and a filled bobbin is removed from one of the upper carriers and placed on this empty spindle. This progresses from one end of the frame to the other, at which time the operation is repeated; and the doillng and donning operation is carried on'without the necessity of rolling a truck up and down the aisle between frames.

In the drawings and specification, there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being defined in the claims.
